addWindow

Adds a window to application.

This call can only happen after the application has started; typically, you should add new application windows in response to the emission of the GApplication::activate signal.

This call is equivalent to setting the property@Gtk.Window:application property of window to application.

Normally, the connection between the application and the window will remain until the window is destroyed, but you can explicitly remove it with method@Gtk.Application.remove_window.

GTK will keep the application running as long as it has any windows.
